Fatigue Killer: An ergonomic design that protects your wrists when using a keyboard for extended periods of time, whether you're typing or gaming. Smooth Feel: Memory foam and a soft imitation leather surface provide a comfortable pillow for your wrist. The surface is easy to touch and wipes clean quickly. The ideal 8° tilt angle and 20 mm pad height ensure that your hand rests naturally on the keyboard without dangling. Take pleasure in typing more comfortably and with less wrist pain. Stable Base: Six non-slip rubbers hold the pad base firmly in place, giving the wrist pad greater stability and giving the impression that the support portion is adhered to the keyboard as a single unit. There are three sizes available: S, M, and L.
